Formyl Derivatives of Amino-Substituted Polyfluorotriphenyl-4,5-dihydro-1H-pyrazoles: Synthesis and Use as Donor Blocks of Nonlinear Optical Chromophores

Abstract

A series of new formyl derivatives of polyfluorinated triphenyl-4,5-dihydro-1H-pyrazoles containing various amine residues in the fluorinated benzene ring have been synthesized and used as donor building blocks in the synthesis of donor–acceptor dyes as potential chromophores for nonlinear electro-optics. Effects of substituents in the donor and acceptor moieties of the obtained chromophores on their spectral characteristics have been studied.
